Postpartum periods

My first period was June 4th-7th. It started out real light, then the next day was more like my normal period with less painful cramping. This evening when I went into the bathroom I had the light pink light bleeding I had when I started my first. Is it normal to have your second period 2 weeks after your first one postpartum? I don’t believe my periods before getting pregnant were regular. I had the occasional missed period. I’m trying to figure out if I need to go in. Of course the clinic & urgent care are both closed for the weekend. I’m on Warfarin for a blood clot, so I was a nervous reck the first time even though the doctors said it would be rare to have an issue.
